Warning signs missed, cries for help ignored - it is a story at the heart of the Newtown school shooting and the Creigh Deeds attempted murder-suicide, but the truth is it happens across the country. CNN's Brian Todd investigates the state of the mental health care system in the United States and finds experts pleading for more resources.

(CNN) - A report on the investigation into the Sandy Hook Elementary School shooting was released Monday, Connecticut state officials announced.

The report, released at 3 p.m. ET, said that police arrived on the scene fewer than 4 minutes after the first 911 call and that the shooter, identified as 20-year-old Adam Lanza, killed himself one minute later.

When something like the massacre in Newtown, Connecticut, happens, you wonder how in the world the parents ever go on? It has been four months now and the grief and pain is more than evident. But underneath, there is something else.

Noah Pozner loved wearing his brown winter jacket. He brought it to school at Sandy Hook Elementary on December 14, the day he and 19 other children were killed.

“It’s the things you hold on to when you have nothing left,” says Noah’s mother, Veronique Pozner.

Noah's parents share their family's story in People Magazine, clutching that same brown coat that a state trooper later tracked down and returned to them. Pozner sums up her grief, saying it's agonizing to see your baby's name on a tombstone.
